Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed November 21, 1910. Serial No. 593,375.

To all whom it may concern:

Be it known that I, HENRY Come, a citizen of the United States, residing at West sachusetts, have invented an Improvement in Picker-Checks, of which the following description, in connection with the accompanylng drawing, is a speclfication, l1ke characters on the drawing representing like The objects of my invention are to provide a simple and inexpensive picker check which can be readily applied to any loom employing a rocker foot, and which will eifectively act to check the movement of the picker in both directions.

I will first describe some embodiments of my invention and then point out the novel features thereof in the appended claims.

Referring now to the drawings, Figure 1 shows the rocker foot, rocker and portion of the picker stick of a loom having one embodiment of my invention thereto; Fig. 2 is a similar View showing a difierent embodiment of the invention; Fig.

-' 14 carries an adjustable collar 19 against 3 is a section on the line m-w, Fig. 1.

I have not deemed it necessary herein to illustrate any portion of the loom except the rocker foot,.rocker and lower end of the picker stick, as the principle and operation of the invention will be readily understood by those skilled in the art without showing any other parts of the loom.

In the drawing 3 designates a portion of the loom frame, 1 the usual rock-shaft sustained therein, 5 the rocker foot carried on the end of the rock-shaft, and 6 the rocker which operates on the rocker foot, and 7 the picker stick which is secured to the rocker 6 in usual way by bolts or other fastenings 8. These parts may be of any suitable or usual laterally to form the seat portion 10 in applied 1 construction and form no part of my present mventlon. Associated which is received a cushion device 11, as shown and described in a co-pending application filed on January 26, 1910, jolntly by myself and R. C. Snow, Se. No. 536,679, which cushion device is adapted to actagainst the under side of the rocker foot, thereby to'check and limit the swinging movement of the picker stick in both directions, all as described in said application.

In my present improvement, I provide the member 9 with the extension 12 which is acted upon by a spring 13 that tends to throw the picker stick into its backward position, as shown in Fig. 1, and which spring takes the place of the ordinary heel strap spring. In the embodiment of the invent-ion shown in Fig. 1 this spring 13 encircles a rod 14 which extends through the extension 12 and which is supported in some suitable way by the rocker foot 5. The heel strap spring is usually supported in a lug 15 which is formed on and depends from the rocker foot 5, andin the embodiment shown in Fig. 1, the rod 14 is adapted to be sustained in this lug, and for this purpose sald rod is provided with an upwardly-bent portion 16 and a laterally-bent portion 17, said portion 17 being securedin the lug 15 by suitable set nuts 18. The rod which the spring 13 abuts.

In the operation of the device when the picking mechanism is actuated to give the picker stick its operative movement, the rocker 6 will rock over the rocker foot 5 in usual manner, and in doing so the spring 13'will be compressed more or less. Said spring 13 will thus act as a means to check the forward movement of the picker stick and the movement of the stick is limited by the engagement of the cushion device 11 with the underside of the rocker foot, it being understood that when the picker stick is in an intermediate position the cushion device 11 does not engage the underside of the rocker foot, but only has engagement therewith when the picker stick is in either 18 tends to return the picker stick to its normal position, and when the shuttle is thrown and strikes the picker the backward movement of the picker stick will be limited by the engagement of the cushion member' 11 with the underside of the rocker, as shownin Fig.1.

The device shown in Fig.1 is adapted to be applied to the rocker foot as now commonly constructed with the lug 15 designed employedfor checking the' movement of the picker stick in b'otl'r directions, As herein shown, the spring 130 is sustained by a rod 140, which instead of being carried by the,

lug'l5 is supported by a boss or lug 150 formed on the hub of the rocker'foot 5.

The spring 130 isco'nfi'ned between an ad justable collar 19 on said rod 'and fthe extension l 2 -as in the embodiment of the inwent-ion shownin Fig. 1 and another; spring 20 is situated'between the extension 12 and the hub'150. Thespring 13 assists inchecking the"-forw;ard movement of .the picker stick, and-the spring 20jassists infche'cking the backward movement thereof. I

In Fig.;-1 I have shown the seat .10 'as formed with the upwardlyadirect'ed portion 21 between which and the body of the memher 9 thecushion'member 11 is inserted. In

Fig. 2 this upwardly 'dire'cted portion 21 ,is

- omitted-andthe cushion member 11 is held in placeby a-rivet or pin 22 which fastens said cushion'mem'ber t0 the seat.

H aving fully described -my inventioihf ;what,' I claim asfnew and desire to secure by Letters Patent is 7 1; In a-picker check, the combination with a rocker foot, of a rocker thereon, a picker stick secured tothe rocker, a'seat portion extending laterally fromthe picker stick beneath the rocker foot, a cushion member sustained on'saidseat and adapted to engage the under side ofthe rocker foot to check.

the movement of the picker stick, an extension from said seat, and a spring acting on said extension. s

2. In a picker check,'the combination with a rocker foot, of a rocker thereon,a picker 'sticksecured to the rocker, a seat portion extending laterally from the .picker stick ing through said. extension, and a spring on the rod acting against the extension.

3. In a picker check, the combination with f a rocker, foot having a'picker stick-receiving. aperture,- of a rocker thereon, a picker stick s'ecuredto the; rocker and extending through said aperture in the rocker foot and below the latter, aplate secured to the' picker stick and extending; through the aperture in the rocker -f0ot andbelow the lower end of the picker stick, the extending end of said plate being-slotted, a rod rigidly securedto the inner end ofthe rocker 'foot and -extendi ng horizontally through the slot of saidextension, a spring 'on the rod acting ion the extension,and an adjustable collar on the outer free end of therod against which the spring acts; and by means of which its tension-may be varied.

4f. ,In'a picker check, the combination with a rocker foot having'a picker-stick-receiving aperture, of a rocker thereon, a picker stick secured to the rocker and extending through-said aperture in the rocker foot and below, the latter, a plate secured to the picker stick and extending through said aperture in the,roc'ker foot and below the lower end of the picker stick, the extending i end 'of said plate being slotted, a rod rigidly secured tothe inner 'end of the rocker 'foot and extending horizontally through the slotof said extension, a spring on the rod acting on the extension, an adjustable" collar on the outer free end of the rod against which the spring acts and by means of which its tension'may be varied, and another spring confined between said extension and' rocker foot. 1 In testimony whereof, I have signed my nametothis specificatiomin the presence of two subscribing witnesses.
